New edition of a text intended for junior-level courses in engineering, and for self-study by practicing engineers. It assumes some basic knowledge of signal models, system models, differential equations, and some laboratory work with physical systems. The difference between signal and system models and physical signals and systems is emphasized, and mathematical results are related to physical systems students are familiar with or can visualize. MATLAB is used in appropriate examples and homework problems which require computation, with the programs used available for download from the Internet. Topics covered include continuous- and discrete- time signals and systems, their state variables, and corresponding time-invariant systems; Fourier series; Fourier, Laplace, and z-transformations and their application in the above systems.
